Description
Performance and reliability
The HPE 789155-B21 is a read-intensive SSD, which means it is optimized for workloads that involve a high proportion of read operations, such as data warehousing and online transaction processing.
In terms of performance, the drive has a sequential read speed of up to 540MB/s and a sequential write speed of up to 500MB/s. These speeds are quite fast and allow for quick access to large amounts of data. Additionally, the drive is equipped with reliable NAND flash memory and has a mean time between failures (MTBF) of 2 million hours. This means that the drive is expected to function for a very long time without failure, which is important for maintaining the uptime of the system in which it is installed.
In terms of reliability, the HPE 789155-B21 is also built with advanced error correction and data retention technologies, which provide a high level of protection against data loss and corruption in the event of a power failure or other types of unexpected events. And it also comes with a 3-year limited warranty, which means that HPE will replace the drive if it fails within the warranty period.
Compatibility With HPE Gen8 Servers and Storage Systems
The HPE 789155-B21 is specifically designed for use in HPE ProLiant Gen8 servers and storage systems. This means that it has been tested and is fully compatible with these systems, and should work seamlessly with them.
HPE ProLiant Gen8 servers and storage systems are designed to take advantage of the latest technologies and are optimized to work with HPE Gen8 SSDs like the 789155-B21. The drive interface is compatible with the 6GB/s SATA interface that is supported by the Gen8 servers and storage systems.
It is important to note that while the HPE 789155-B21 may physically fit into servers and storage systems that are not Gen8, it may not be fully compatible and could lead to issues with performance and reliability. Therefore, it is important to confirm compatibility before installing this drive in any system.
Management and maintenance
The HPE 789155-B21 SSD can be managed and maintained through the use of HPE’s Smart Storage Administrator (SSA) software. This software allows you to monitor the health, performance, and status of the drive, as well as configure and update its firmware. Additionally, it also provides a way to check the drive’s SMART data, which provides information about the drive’s health and performance status and allows you to predict potential issues.
The drive can be replaced easily, and the replacement procedure is straightforward. The drive is designed to be hot-swappable, which means it can be replaced while the system is running without interruption.
It’s also important to keep the firmware of the drive up-to-date. Firmware updates can improve the performance, security and reliability of the drive and can fix any known issues. HPE releases firmware updates on a regular basis, and it is recommended to check for updates and apply them when they become available.
In terms of physical maintenance, the drive should be kept in a clean and dust-free environment, and proper care should be taken to protect it from physical damage. The drive should be handled carefully to avoid any physical damage to the connectors or other components.
